What size are Shimano chainring bolts?
Outer diameter of male bolt across threads is 7.7mm, outer diameter of female sleeve/nut is 9.6mm. Diameter of both across the pan head is 11.6mm. These are the measurements for a Shimano 5700 compact crank 50/34 stock chainrings, for future reference.
Should I use threadlocker on chainring bolts?
Chainring bolts don’t need much torque and they rarely come loose (i’m inclined to say never). Loctite will just make removal more difficult, and generous coat of grease will prevent corrosion just fine in practice.
Are all chainring bolts the same?
Each chainring bolt – the number will vary depending on the chainset design, but is usually four or five – consists of two parts, a female-threaded ‘outer’ part and a matching male ‘inner’. The outer nut has a standard external diameter of 10mm so theoretically the bolts can be used to fit any chainset.
What is the blue stuff on screws?
Thread-locking fluid or threadlocker is a thin, single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion.
Do Shimano chainrings come with bolts?
The thing is that the bolts needed for the BB were a larger diameter than the ones with crank, so those are the ones I used. But every time I have bought a Shimano BB, they come with bolts, and every high end Shimano crankset also tends to come with bolts.

What are the best chainrings for a 9 speed Ultegra?
This is only an issue with triple cranksets. My most popular chainrings are 48 – 38 – 26 and 24 tooth replacements for Shimano’s 9 speed Ultegra and 105 triple cranks. This makes for a much better range of gears if you’re touring.
What chainrings are compatible with Shimano road triple cranksets?
For chainrings compatible with Shimano road triple cranksets, like Dura Ace, Ultegra, 105 and Tiagra, scroll down to the TA Alize 130mm rings for the middle and outer positions. Then scroll to the TA Zelito 74mm rings for the inner (triple) position. If you are using STI, you’ll need to use a Shimano derailleur specifically designed for STI.
